Thanks for you input ses. It is a little harsh but this is what we wanted - real opinions from real people. I agree with you that a presentation should reflect the person giving the presentation but in terms of content & story to be told, the design itself can be tricky and time consuming.
No worries, I am just one person who doesn't fall into the target market for your product - there may well be many valid scenarios where a having template, particularly with a good design could be useful. There are all kinds of different presentations requiring slide decks so maybe you just need to find the right niche?
